OU virologist explains how vaccines work and if booster shots will be needed – Tulsa, Oklahoma

Tulsa, Oklahoma 2021-08-05 22:23:50 –

Health professionals continue to increase the number of people vaccinated as the Tulsa-Delta variant in Oklahoma contributes to the increase in the number of COVID-19 cases in the state, but doubts about the sustainability of the vaccine’s immunity. Some people want to know if they have booster immunity. I need a shot.

Immunology experts say they are still studying why some drugs provide high levels of long-term immunity, while others do not.

Dr. James Papin, a virologist at OU Medical College, said the idea of ​​a vaccine is to introduce the immune system into some of the infectious agents without being exposed to them. He said the vaccine helps our immune system recognize the virus and build immunity to it.
For Moderna and Pfizer vaccines, that information is known as mRNA, also known as messenger RNA. According to Papin, messengers can inform cells about the composition of COVID-19 and develop an immune response.

“And that’s the basic information your cells are already using to produce all the proteins your body needs to survive, so they take that information and give it to your cells. I put it in, “he said.

According to Papin, the Johnson & Johnson vaccine uses a replication-deficient viral vector that can put information into cells, allowing cells to produce proteins to develop an immune response.

Each vaccine uses a different method, but Papin said all three vaccines have proven to be effective.

“Complete eradication of the COVID-causing virus SARSCOVID-2 was not always the goal. The goal was to stop hospitalization and death, and current vaccines do not have to have that third booster. It’s very effective at the goal, “Papin said.

Vaccine companies are discussing booster shots, as some data show that antibodies begin to decline after some time, Papin said. He now said it was too early to know if and when we needed it. But he wants to clarify that the need for booster shots does not mean that the double-dose regimen vaccine does not protect you from serious illness.

“As we get more data and move further away from the large number of vaccinated individuals, they see what their immune and long-term immune responses look like, and how protective they are. You can do research to track down, “he said.

Vaccine companies are still studying booster shots, but Papin said they could be recommended to vulnerable people.
